In addition to its very capacity to generate energy (solar thermal and solar photovoltaic energy), the sun is the source of all renewable energies.
Thus, the heating of the earth and water causes pressure differences that give rise to wind, the source of wind energy. The sun is at the same time the main agent of the water cycle, which turns the ocean evaporation into rain and, therefore, a hydropower resource.
The sun is also the major player in the process of photosynthesis and therefore, the main source of energy using biomass.
The sun is ultimately the source of life on the earth and we must take advantage of its energy and those transformed by nature thanks to its influence.
